Abstract

The invention discloses a ship industry knowledge graph construction and analysis method. The method comprises the following steps of: pre-defining a relationship between entities, and constructing a mode graph of a ship industry knowledge graph; obtaining knowledge according to the constructed mode graph, and obtaining the entities and relational data of the ship industry and links between the entities; performing knowledge fusion on the obtained entities and relational data, and performing entity alignment, entity disambiguation and data classification on the data; performing knowledge storage on data obtained after knowledge fusion, storing the data into a relational database so as to process the data, and storing a processed triple into a graph database to form a ship industry knowledge graph; and finally, based on the ship industry knowledge graph, analyzing a ship industry structure from three aspects, namely, regional industry layout, enterprise community discovery and focus enterprise discovery, and updating the predefined entities in the mode graph and the relationship between the entities based on an analysis result. According to the method of the invention, research and management of a ship industry cooperation network are facilitated.

Description

Technical field [0001] The present invention belongs to the technical field map knowledge, relates to analysis and mapping knowledge shipbuilding industry cross-technology, and more particularly relates to a marine industry knowledge map construction and analysis. Background technique [0002] In recent years, the degree of specialization and complexity of the supply chain of the shipping industry have become increasingly demanding, forms of cooperation between the shipping companies are also more diverse and complex, such as business investment, supply relationships and economic relationships, its scope of cooperation has gradually spread from north to south along the coast, along the Strip into the surrounding area, forming a divergent pattern of industrial network. The existing research on aspects of the shipping industry for more research to analyze from a single perspective of cooperation, ignoring the complex network of related industries. Requiring a new perspective to stu...
